A bipolar transistor amplifier stage is shown in Fig. 21.20 and the

transistor has characteristics, shown in Fig. 21.21, which may be

considered linear over the working range. A 2.2 k resistive load

is connected across the output terminals and a signal source of

sinusoidal e.m.f. 0.6 V peak and internal resistance 10 k is connected

to the input terminals. The input resistance of the transistor

is effectively constant at 2.7 k. Determine the current, voltage and

power gains of the stage. The reactances of the coupling capacitors

C1 and C2 may be considered negligible.
